One of my most popular little games, Dungeon Hero, is in the itch bundle for Ukranian hospitals.
The bundle is a 252-game bundle for only $8, containing scores of cool indie RPG's, adventures, VTT assets, etc.
If you like indie RPG's at all this bundle is a steal, with things like Mausritter, Cairn, a WildSea expansion, LordSworn, and many other tidbits.
